Based in Switzerland with clients around the world, MPI offers products, R&D services and consultancy in high power ultrasonics, a range of top quality ultrasonic cleaning and sonochemistry equipment and special equipment development for new applications. Learn more about the company here.

We wish to establish strategic project partnerships for the development of atomic energy projects related to the safe decontamination and passivation of radionuclides in water. MPI Ultrasonics has extensive experience with ultrasonic liquid-processing units and technology, including customized design and applications experience using “MMM Ultrasonic Technology”. Vinča Institute for Nuclear Sciences has wide-ranging expertise in Radionuclides and Material science, both theoretical and laboratory work. Together we are ready to address large-scale polluted water decontamination caused by accidents in nuclear power plants.

We wish to make contact with companies specializing in stem cell research and commercial exploitation for the purpose of developing new and enhanced processes which will improve outcomes for patients. Our objective is to combine the known benefits of ultrasonics and stem cell therapy. Existing equipment for laboratory-scale liquid processing and for therapeutic massage can be readily adapted for use with stem cells, during growth and preparation and after injection into the patient. Laboratory trials will evaluate the effects of ultrasonic agitation during stem cell culture and clinical trials will determine the benefits of ultrasonic stimulation after injection.

The quality and competitiveness of casting strongly depends on the quality of molten alloy and the technology used to produce it. With regards to quality, the casting of aluminium alloys is not easy, since alloys are prone to dendritic and heterogeneous structures, as well as the absorbtion of hydrogen during melting, which requires a specific melt processing operation in order to reduce and control the level of porosity in a microstructure after solidification. By H. Puga, M. Prokic, N. van Dongen.

Ultrasonic systems for the most demanding applications: "MMM Technology" (Multifrequency, Multimode, Modulated Sonic & Ultrasonic Vibrations) gives the best possible results in ultrasonic cleaning and sonochemistry systems as well as making many new applications possible (***MORE***). For the first time any complex mechanical system up to a mass of several tonnes, consisting of arbitrary resonating elements, can be driven efficiently (Learn more about MMM Power Supplies)

Please see also this video of fluid rotation by ultrasonics - another effect in metal processing in addition to degassing, homogenization, crystallization, grain refining. Here water and coffee particles are used to demonstrate the effect in the lab, but in reality liquid metal also rotates during processing.

Our tube reactors, also based on MMM Technology, are ideal for all through-flow sonochemistry applications providing high intensity, uniform sonication under your complete control. Various sizes available.

An unusual application for ultrasonics - atomization of molten metal alloy. The sonotrode uses a special tip (which is different for atomizing different metals) and water cooling. More information.

Foil immersed for only a few seconds in a benchtop ultrasonic reactor powered by MMM technology. The extent and uniformity of the perforation cannot be matched by any conventional ultrasonic system. The details page includes a small animation and the complete video clip is available for download on our download site.

For high-energy ultrasonic cleaning and sonoreactors, if MMM technology is not required, we also offer this range of top-quality "Push-Pull" transducers (tube resonators), driven by modular generators to suit all power requirements.

We have developed equipment for major manufacturing companies in Switzerland and around the world. Here are some examples:

This is a short video of our prototype ultrasonic compaction unit for reducing the volume of powders in the pharmaceutic industry. (File size 1.5Mb. You may need to download the file first - Right click, "Save target as" and / or download Apple Quicktime).

Another application of MMM Technology - prototype equipment for proving a process of ultrasonic cleaning in supercritical liquid CO2 (more).

Prototype equipment for ultrasonically assisted extrusion of composite plastics. MMM Technology allows the application of ultrasonics directly at the extruder head (more).

A SERIES OF EXTRAORDINARY AND UNIQUE BOOKS RECOMMENDED BY MPI

Coupled Tensors of Piezoelectric Materials State

Dr. Ljubisa Peric, Author

Some researchers spend a lifetime working towards the understanding of a specific complex problem and, as the culmination of their career, write a technical work offering such a profound and multilevel insight that it could not have been produced in any other way. Our contemporary lifestyle imposes enormous barriers against creating such life-career books, yet this is one. This extraordinary book provides incomparable understanding of piezoelectric materials and their behavior in electro-acoustic transducers.

Dr. Peric's book is available in English exclusively from MPI. To order the book, please use our online store, or read more here.

Special offer price for ordering 2 or 3 books together:
